which of the following expresses the possible number of positive real

solutions for the polynomial equation shown below?

x^3 - 4x^2 – 7x+ 28 = 0

o

a. three or one

b. two

c. one

d. two or zero

Two or zero expresses the possible number of positive real  solutions for the given polynomial equation.

Option D

Step-by-step explanation:

Given equation:

First, we put hit and trial method to find out the one solution. So, if we put x=4 then the above expression will become zero.  We can also write the above expression as  

We know the formula, , make use of this, we get

So,

Hence, from the above expression, we have three values of x as x= 4, 2.64 and -2.64

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
